RUBBER NOzzLE FOR CLINICAL EINDV LIKE PURPOSES.

Application. filed January 26, 1927,\Serva1 No. 163,745, and in Italy LJanuary 30,` 1927.

My invention has for its object a rubber nozzle adapted to fit through its larger end mouthpiece the neck of a bottle, flask,-or

the like, and provided with an external pas-`v sage for therblowing Ofi' of thel air. My

invention aims to provide a vnozzle which will allow the liquid in the bottle or the like` to uniformly flow therefrom, when the bottle is turned upside-down, while avoiding any whirlings, bubblings, eddyings or turbulence of the nozzle, so that the liquid will flow with continuity and as uniformly as possible.

Besides generical, vtechnical or laboratoryk applications, a nozzle accordingy to `my invention is particularly adapted for medical purposes, such as irrigations, clysters, and

the like, requiring the use of sterilefand aseptic liquids. For this purpose, Iy lit the nozzle on the mouthpiece of the bottle (burette, Florence flask, Orthe like) used for boiling water and /orl dissolving chemicals or the like, and then I slip a usual rubber hose over the nozzle outlet, so that I may immediately utilize the bottle or the like for.

without pouringftheirrigations or clysters, liquid from its container to any other nonsterilized receptacle, thus operating under' the best aseptic conditions.

An embodiment of my mventionri's shown l of example in the annexed drawing.Y Fig. 1 is a side view, Fig. 2-a'vert1cal sec-- an enlarged belly 3 in which opens a narrow Y side passage 4, and anoutlet 5`having ya flanged edge for receiving and. retaining a connection to thehose. y

liquid at the outletv of thel PassageV 4 ends externally with an. en`

larged funnel-shaped mouthpiece, wherein it is advisableto enter a lump of lilter wadding or gauze.

Subsequentk .to the enlargement in section of belly 3, the throttling of outlet 5 and' the relatively very narrow passage 4, the latter merely acts as an air blast or exhauster, for

required to replace the discharge liquid,.

while outlet Any boiling liquid therein,

the latter isplowing OI through'the 5 and the irrigation hose, not shown'. buretteilask, or the like, adapted for may be ittedwith my improved nozzle over its mouthpiece, to be directly utilized, by `merely reversing it upside-down, for any clinical, laboratory, ory like purposes, without pouring the sterilized liquid therefrom.

What I claim is: 1. A rubber nozzle forth,

of the character set comprising a cylindrical neck portion,

an enlarged belly, a narrow air passage at belly,

sage.

2. body `the sidek of the neck and opening in said a tubular outlet member vfor connection of said belly portion to a Vrubber hose, and an enlarged funnel-shaped in-let at the `opposite or ,outerend ofsaid narrow pas,-

A. rubber nozzle comprisinga hollow having at one end a cylindrical neck adapted to fit upon the neck of a bottle, a

reduced tubular outlet at its other end adapted to receive a hose, an enlarged portion between the neck and outlet, and an air passage leading from the outer end of the neck into the enlarged portion, the outer end of said passage being enlarged to adapt it to receivea filtering material.

testimony whereof, I aiix my name `this 8th day of January, 1927.
